Thanks, I think I understand. I'm not sure I have a good response.
It can be rough integrating a single chicken. If you give your friend the cockerel, your pullet will be by herself. They like to have a buddy, the older hens may not accept her for a few more months. If you had two or more pullets I'd say go ahead, but since you only have one I'd want to keep him another three or four months to give the pullet some time to grow up so she can join the flock.
When you give the cockerel to your friend it is up to them to integrate him to their flock. I don't now what your friend's flock or facilities look like or how much experience integrating chickens they have. When you give him away he is no longer your problem.
